This addon allows registered users to save their job searches and create alerts which send new jobs via email daily, weekly or fortnightly. Job Alerts provides you with a new shortcode to add to your pages which gives logged in users an alerts management page to add, preview, enable, disable, edit and delete email alerts. Alerts can be configured based on keywords and job types.
This is the EXACT same plugin as distributed by the developer on WP Job Manager. The developers’ links are provided above.
